A Kernel of Inconvenient Truth

California scientists have tracked air pollution using 70 cornfields in 30 states.

The UC Irvine scientists came up with the idea as a way to complement air samples.

Corn is grown just about everwhere in the US. It's an annual plant -- so all the carbon dioxide contained in the corn is from a single year.

Their research led to finding the Ohio Valley and California having the most carbon dioxide. Colorado had the least.

Mapping gas using corn.

Hmmm. I would have though they'd have used beans. (UC Irvine)
